What you first want to do is to become closd friends with gaurds at the borders to the point where you are alone with you whike they have their uniform. They also have to not interact with the other gaurds. Once this happens, kill him, take his uniform, make sure the last name sounds like it matches your race, and then start working there, and collecting his paychecks, so you instantly have a source of income. Build up enough money while living on the other side kf the border (where you are not a citizen) and then buy citizenship to the country.
I will tell you uys how to get away with murder in a future post.
